Trop Kick
this move has very a similar effect to moves like Mystical Fire and Skitter Smack, while having a similar base power to them. if those move could be given to a decent amount of Pokémon, why can't this move be given a similar treatment?
Zing Zap
this move is probably one of the most mundane signatures move out there, it is a clone of the fairly normal move iron head. The description of the move also sound like something that could be done by pretty much any electric type pokemon
The user crashes into the target, delivering a powerful electric shock. This may also make the target flinch.
This one is extra annoying since most electric type are stuck using wild charge for a physical move. This move might have a different name or description in Japanese that is more specific with it's flavor, so increasing distribution might be harder than I think.
Spirit Break
This move is pretty similar to the situation with trop kick, but somewhat more annoying since this only one of two physical fairy moves in the game.
Leafage, Branch Poke
I think this two moves were made so the grass starter could have a base 40 move like the other starters can have with ember and water gun. These two could be given to a lot of grass types as a grass type move when at a low level.
Volt tackle
This move is just electric type double edge.
I think wild charge is actually kind of a neat concept when it is given to a non electric type Pokémon a strong coverage move at the cost of taking damage. But for electric type they should just have access to a normal electric move and have volt tackle as a additional option.
